The complete mitochondrial genome of the Chinese noodlefish Leucosoma chinensis and phylogenetic analysis of Salangidae (Osteichthyes: Osmeriformes)

Abstract

In the present study, we obtained the first complete mitochondrial genome sequence of Leucosoma (Salanx) chinensis. It was 16,595 bp in length and consisted of 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and a non-coding control region. The nucleotide composition was A (23.1%), T (25.2%), G (20.0%) and C (31.8%), and the A + T content (48.3%) was a little lower than G + C content (51.80%). Phylogenetic analysis of 10 species of Salangidae identified three major clades. These results may facilitate the future genetic research of L. chinensis and Salangidae.
